What term is best used to describe water suitable for drinking and cooking?

The term that best describes water suitable for drinking and cooking is "potable." Potable water meets health and safety standards for consumption and is free from harmful contaminants. It is essential for public health as it can be used safely without the risk of waterborne diseases or illnesses. In many jurisdictions, potable water is treated and tested to ensure its quality, making it a critical resource for households and establishments that require safe drinking and cooking water.

Other terms like non-potable refer to water that is not safe for drinking or cooking, while contaminated describes water that has been polluted or infected with harmful substances. Recycled water, while it can be treated and potentially made safe for certain uses, is typically not classified as potable unless it has undergone extensive treatment specifically to meet potable standards.
